More particularly, the invention relates to treatment and improvement of symptoms related to addictive disorders, psychoactive substance use disorders, nicotine addiction, and tobacco addiction.

[0003] 2. Description of Related Technology

[0004] Several classes of compounds have been described for the effective treatment and management of the diseases fibromyalgia (FMS) (or fibromyalgia syndrome) and Chronic Fatigue Immune Disorders Syndrome (CFIDS) or Chronic Fatigue Syndrome (CFS). More particularly, heterocyclic amine type compounds, phenylazacycloalkane type compounds, cabergoline and cabergoline-type compounds have been described for the effective treatment and management of these neuromuscular conditions.

[0005] Heterocyclic amine compounds and methods of making the same are disclosed in U.S. Pat. No. 5,273,975, issued Dec. 28, 1993; U.S. Pat. No. 5,436,240, issued Jul. 25, 1995; U.S. Pat. No. 5,462,947, issued Oct. 31, 1995; and U.S. Pat. No. 5,594,024, issued Jan. 14, 1997. More particularly, the compounds and the processes for making those compounds, formulations and methods of preparing medicaments are described in U.S. Pat. No. 5,273,975, issued Dec. 28, 1993; and U.S. Pat. No. 5,436,240, issued Jul. 25, 1995, also providing a generic description of compounds having use in the treatment of FMS and CFIDS.

[0114] Any conventional pharmaceutical preparations can be used, e.g., consisting essentially of an inert pharmaceutical carrier and an effective dose of the active substance; e.g., plain or coated tablets, capsules, lozenges, powders, solutions, suspensions, emulsions, syrups, suppositories, transdermal patch, and other useful mediums for delivering the active agent. Preferably, the active agent is formulated into oral dose tablets.

[0115] Preferred oral dose tablets comprise the active agent and a pharmaceutically acceptable carrier. The preferred pharmaceutically acceptable carrier can comprise one or more inert excipients, for example, mannitol, maize starch, colloidal silica, povidone, and magnesium stearate.

[0116] Tablets containing heterocyclic amine compounds, phenylazacycloalkane compounds, and cabergoline or cabergoline-type compounds typically incorporate, in mg/tablet, the following amounts of active agent: 0.125, 0.25, 0.5, 1.0, 1.25 and 1.5 mg. The preferred starting dose for the administration of these compounds is about 0.125 mg/day, provided to a patient three times per day (tid). The dose may be increased from the initial dosage to a higher amount with increases every five to seven days up to a maximum dose of 10 mg/day. A preferred higher total daily dosage is about 6 mg/day. A more preferred higher dosage is about 4.5 mg/day to 5 mg/day.

[0117] Dosages of the aromatic bicyclic amine compounds can be from about 5 mg of the aromatic bicyclic amine active agent to about 120 mg of the aromatic bicyclic amine active agent per day. Preferably, an aromatic bicyclic amine active agent is administered in an amount of about 20 mg/day to about 100 mg/day. More preferably, an aromatic bicyclic amine active agent is administered in an amount of about 40 mg/day to about 80 mg/day. The aromatic bicyclic amine compounds, like other compounds suitable for the invention, can be administered at an initial dose strength that is later increased to a suitable maximum daily dose.

[0118] For treating the addictive disorders described herein the drug may also be provided in chewable format, such as a chewing gum. The amount of active drug included in a chewable base may be half the dosage suggested above for the tablet, for example starting with about 0.075 mg of cabergoline per square of chewing gum being administered tid and followed with higher levels after the patient shows tolerance to the drug. Chewing gum dosages contemplated within the scope of the invention include at least 0.075, 0.10, 0.125, 0.150 mg/day, in addition to those mentioned for a tablet for heterocyclic amine compounds, phenylazacycloalkane compounds, and cabergoline or cabergoline-type compounds. Similarly, dosages contemplated for the aromatic bicyclic amine compounds include from about 2.5 mg/day to about 125 mg/day. One or two chewing gum squares can be provided to the patient up to three times a day, depending on the therapeutic need of the recipient.

[0119] Transdermal administration, such as with a skin patch application, and inhalation therapy, such as with an inhaler, also are foreseen where the patch or inhaler would deliver desired levels of the active agent to the patient. A transdermal patch containing the active agent also could be combined with a patch containing nicotine to eliminate a patient's craving for tobacco-containing products.

[0120] The drug first is typically administered to a patient at a low dosage to avoid possible nausea that may occur with higher starting doses. The dose is then titrated up to higher levels until a suitable therapeutic effect is achieved.

[0121] The effective dose range can be from 0.01 mg/day to about 10.0 mg/day per patient for a heterocyclic amine, phenylazacycloalkane, cabergoline, or cabergoline-type derivative. The preferred effective dose is an amount of the active agent between about 0.125 mg/day and about 6 mg/day. The more preferred effective dose is an amount of the active agent between about 0.375 mg/day to about 5 mg/day. An especially preferred effective dose is an amount of the active agent between about 0.75 mg/day and 4.5 mg/day to a patient. In addition to being administered by oral or intravenous route, the active agent also can be administered transdermally or by inhalation.

[0122] In the practice of the invention, typically a starting dose of about 0.125 mg/day, administered three times per day, is incrementally increased every five to seven days until optimal therapeutic effect is achieved. The dosage can be titrated to achieve a maximal therapeutic effect, provided that the patient does not experience intolerable side effects. One ordinarily skilled in art of providing medicine, such as a physician or pharmacist can determine the optimal dosage level after considering a patient's age, size, medical history, responsiveness to and toleration for the drug.

[0123] Addictive disorders and psychoactive substance use disorders, such as intoxication disorders, inhalation disorders, alcohol addiction, tobacco addiction and/or nicotine addiction can be treated according to the invention. Tobacco and nicotine addiction would be treated with the goal of achieving either smoking cessation or at least a reduction in the intake of tobacco and/or nicotine. General descriptions of addictive disorders, including disorders related to intoxication, inhalants, and tobacco addiction or nicotine addiction can be found in many standard sources. The addictions and behaviors that can be treated by the invention generally are further described in, for example, The American Psychiatric Press Textbook of Psychiatry, Second Edition, edited by Robert E. Hales, Stuart C. Yudofsky, and John A. Talbott, 1994, incorporated by reference, especially pp. 401 et. seq., section on “Nicotine” incorporated by reference; and Manual of Psychiatric Therapeutics, Second Edition, edited by Richard I. Shader, incorporated by reference, especially pp. 85 from Chapter 11, entitled “Hypnosis”.

[0124] The method is particularly useful for the treatment of and relief from alcohol and other psychoactive substance use disorders such as, for example, disorders related to intoxication or inhalants, more particularly tobacco or nicotine addiction. The effect of the invention on tobacco addiction more particularly involves the administration of the active agent in a manner and form that reduces the symptoms of the disease. In particular, the tobacco- and/or nicotine-related aspect of the invention can be used to reduce or stop the smoking or chewing of nicotine-containing materials by a patient.

[0125] Without further elaboration, it is believed that one skilled in the art can, using the preceding description, practice the invention to its fullest extent. Those skilled in the art will promptly recognize appropriate variations from the procedures both as to reactants and as to reaction conditions and techniques.
